Two mechanical vibratory units are fitted to the tub, one at each end, and are powered by two independent electric motors thus producing even distribution of energy to the stainless steel ball
mass.
The capacity of these machines can vary from 17 up to 2000 liters

The rectangular tub machines type VBL are used for deburring, smoothening and polishing operations of parts of medium/big dimensions.
The tub of the machine, lined with highly wear resistant hot cast polyurethane, can be manufactured with a capacity from 220 up to 2500 liters.

Three dimensional vibration enables the media and parts to rotate uniformly and continuously.
The special bowl shape greatly reduces the risk of damage to the parts. On the completion of treatment a flap is operated either manually or pneumatically and separation starts.

The VBTH machine can be introduced into production lines in a semi-automatic or automated state.
PLC controlled production lines (the unload facility operated pneumatically) can in a lot of cases take the raw product and completely process it (including separation, washing and drying).

The VBT machine is recommended for the processing of medium/large items, where automatic unloading does not have any particular advantage or where unloading over a dam and screen may cause damage to delicate parts. In addition, where the machine is to be used for a variety of parts of different sizes and batches, an auto-unload machine has no real advantage over the VBT.
